Could not find any real clear DIY for this mod so here is my attempt at it.
Allen wrench from bike tool kit
Something to cut the plastic (Dremel, Saw, Util. Knife)
Rear Stand (not necessary, but good to have)
Difficulty level (1-5, 5 being hard): 2
1. Put bike on rear stand
2. Remove Passenger pegs, exhaust, stock chain guard.
3. Make necessary modifications (Cut and drill), shown in pictures below
4. Install Hugger
5. Put bike back together.
NOTE: The last cuts (on the inside where my rear shock is) is not needed if you have the stock rear shock. Instead, you will need to simply notch a clearance for the chain guard guide/holder.
Here is some pics before modification and installation:
